Details

Powered via the USB connection or with an external power supply. The power source is selected automatically.

The ATmega2560-16au has 256 KB of flash memory for storing code (of which 8 KB is used for the bootloader), 8 KB of SRAM and 4 KB of EEPROM (which can be read and written with the EEPROM library).

Comes preburned with a bootloader that allows you to upload new code to it without the use of an external hardware programmer. It communicates using the original STK500 protocol (reference, C header files).

This version is optimized in the original version, both to ensure consistent and compatible with the original, but also easy to use.

Technical Details

The Mega 2560 R3 Board is 100% compatible with Arduino.

The Mega is a microcontroller development board based on the ATmega2560. Thanks to the bootloader, it is possible to download programs directly via USB without going through other external writers. The power supply can be powered by USB directly or by using an AC-to-DC adapter and battery as an external power supply.

Based on the open source code principle, you can download and use it for free in topic production, school teaching, motor control, interactive works, and so on.

Well this did the trick, I have so much fun playing with this. By DCA 2016-05-05 16:43:45

I got this to start my own project of Computer Controlled Christmas Lighting. Well this did the trick, I have so much fun playing with this. The coding is a cinch to work out but for the most part you can find nearly anything you need in the online library or forums. Will probably get another soon for more playing.

I've bought a bunch of these over the last year for various projects, and they've all worked great!By Jason 2016-05-05 16:36:17

A quick side-note: I noticed a number of idiots posted reviews claiming these to be "counterfeit", however what they failed to realize is that these do not claim to be the official "Arduino" board. It is the SunFounder version, which is stated in the listing and on the board. They are 100% compatible with the Arduino environment, and functionally identical. The wonderful thing about Arduino is that it is an open-source platform, thus anybody can make the boards and sell them (or tweak them if they wish), which is great because it means we can get them cheaper! The only thing one really needs to consider is whether other manufacturers produce boards of the same quality, and in my experience, having bought a lot of SunFounder stuff, I've found their quality to be top notch!

This is the genuine made in Italy arduino mega.By William R. Sweeney 2016-05-05 16:35:06

As an electronics product development engineer, I once discounted the utility of these devices and their "shield" ecosystem. Was I ever wrong. This is the platform for rapid prototyping of Atmel based products, not just for hobbyists.

Things that took days or weeks to create now take hours thanks to the enormous libraries and example code in the arduino community.
